WINDOW-CLEANERS SCAFFOLCD AND CHAIR.

Application filed April 11, 1933. Serial No. 31,404.

ToaZZ whom it may concern! Be it known that I, BENJAMIN B. Do-

LARo, acitizen of the United States, residing at New York, in thecounty and State of New York, have invented new and useful Improvements in \Vindow-Cleaners S'caf-' folds and. Chairs, of which the following is near the rear edge thereof, and to said loops a full, clear, and exact specification.

This invention relates to WlIlClOW scaffolds and-chairs, and has for its object to provide a seat which may beconveniently and securely fastened on a window sill for use by windowele'aners, and which may also be applied to a stand or stool for use as an ordi-.

nary chair.

A special object of the invention is to provide a seat with tapered blocks or strips secured below it for supporting the samein proper position on a window sill for use by window cleaners, said blocks or strips being also formed to engage and interlock with the top member of a stand or stool, whereby the seat may be interchangeably used on the window sill for window cleaning or on said stand or stool, thereby providing an everyday use for the seat as a chair when it is not being used as a window cleaners scaffold.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure 1 is a vertical sectional view of a showing my improved seat or scafi'old secured thereto.

Figure 2 is an elevation of the window and sea-t looking from the outside. Figure 3 is a side elevation of the seat applied toa. stand or stool to form an ordinary chair. I

Figure 4 is a plan view of said chair.

Figure 5 is a section on the line 55( of Figure 4, and

Figure 6 is a section on the linen- 6, of Figure 4. p

In Figures 1 and 2, 1 designates a window frame and'2 the outer sill, which may be made of stone or masonry. The seat 3 may be shaped to conform generally to that of an ordinary chair, and is preferably provided with a curved back The rear and lateral edges of said seat 3 are protected by a channeled metal strip 5 which may be shrunk or otherwise secured to said edges as shown in Figures 4, 5, and 6.

From said channeled edge member 5 loops' or eyes 6 roject at opposite sides ofthe seat ch-a ins are provided with hooks or other suitable means 8 to detachably engage loops or eyes 9 projecting from the side members of the window frame 1 at a distance above the sill. Hooks 10 are hinged in eyes 11 projecting from the channeled edging member 5 at opposite sides of the seat 3 near the sill, as shown best in Figure 1.. When the hooks 10 are engaged with the eyes 12, and the hooks 8 on the chains 7 are engaged with the eyes, 9, the seat 3 is securely fastened to the window frame and constitutes a safety scaffold for use by window cleaners.

The seat 3 is supported on the sill 2 preferably in a slightly inclined position, as clearly shown in Figure 1, by Ineansof a pair of blocks or strips 13 which are suitably tapered to support th outer or rear edge of said seat at a higher level than the inner or front edge thereof. The arrangement of the seat so that it is inclined as shown has a tendency to throw the body of the window cleaner inwardly, that is, toward the interior of the room, and thus renders the scaffold safer for his use.

The tapered blocks or strips 13 are preferably secured to the seat 3 with their rear ends converging toward each other, and the inner faces of said strips or blocks adjacent the bottom surface of the seat are beveled as at 14, forming a dove-tailed interlocking connection with the correspondingly beveled lateral edges 15 of the top member 16 of a stand or stoolbest illustrated in Figures 3, 5, and 6. Said stand or stool 16 com prises ordinary chair legs 17 and braces or rounds 18 in addition to the top member 16, and when the seat 3 is applied to said stand or stool with the beveled inner faces 14 of the strips or blocks 15 frictionally engaging the edges 15 of the top 16 of said stand or stool, an ordinary chair is provided, as best shown in Figure 3. When the seat is used to form a chair, the hooks 10 may be swung backward and engage with lugs or pins 19 projecting at the proper points from the metal edging member 5, see Figures 3 and 4:.

It will be readily observed that my invention constitutes all that is required to produce a strong and safe scaffold and also a substantial chair, andthat the several parts and means employed may be diseninto an ordinary chair when desired.

2. A window scaffold comprising a seat having rear and lateral edges bound with metal edging, hooks hinged to said metal edging and adapted to detachably fasten the seat in convenient position on a window frame, lugs projecting from said metal edging for supporting the hooks when they are not used for fastening the seat to the window frame, and means for supporting said seat when mounted on a window sill.

8. A combined window scaffold and chair seat having tapered strips for supporting the same on a window sill, the inner faces of said strips being beveled to interlock with a stool for forming a chair when not used as a scaffold.

4. The combination with a window scaffold seat having strips for supporting the same on a window sill, said strips converging from the front edge toward the rear edge of the seat, and the inner faces of said strips being beveled, of a stool having a top member provided with correspondingly inclined and converging edges to be engaged by said strips for the purpose specified.

In testimony whereof I have signed my name to this specification.

BENJAMIN B. DOLARO.
